HEATING UNIT Filed may 28, 1926 iine 2-2 oi appease@ aies ii invention relates to eating systems y and particuiariy te radiators means contr liing the operation of the radiators.

The invention has `among its other objects the production ci apparatus of scrihed which is compact, convenient, du`- rable, ei'iicient and of simplied construction.

particular object of the invention is to provide improves means :for controlling How ofair around or'through a radiator core.

@ne iorin of the'invention is embodied in a radiator comprising a housingy in the lower end oi.a which a radiator core is disposed, the arrangement beine' such that air may enter 'the iovver end or the housinc and pass out the upper end thereof. rilhe operation of 'the radiator is controiled by means of an adj abie damper which contr-ois the dow o through the housing, theI damper preierabiy comprising a pivoted plate which is connected by Worin gearing to handle or knob to permit adjustment of the damper.

Another form of the invention is embodied in a radiator of substantialiy the same construction as the radiator described above, the

pivoted damper being replaced by a damper comprising a rolled partition which may be unroiied to regulate the lflow oi air through the radiator.

Many other objects and advantages oi the construction herein shown and described vviii be obvious to those skilled the art from the disclosure herein given.

To this end invention consists in the novei construction, arrangement and combination of parts herein shown and described, and more particuiarly pointed out in `the claims.

in the drawings, wherein iike reference characters indicate like or corresponding parts:

Fig. 1 is a verticai section takenthrough heating apparatus embodying 'the invention;

Fig. 2 is an enlarged plan section taken on Fig. 1;

Fig. 3 is a section taken Fig. 2; and v Fig. d is a fragmentary section taken through apparatus embodying another torni oi the invention.

on iine 3 5 oi the kind de# e s Beierring for the present to Figs. 1 to 3,

inclusive wherein i have iilustrated one forni of trie invention embodied in a radiator device adapted to he positioned in a roon: or the like, the reference character 10 designates generally a housing supported by a plurality of legs l1 in such manner that air may e ter the lower end of the housing and pass through a radiator core 12, the air being discharged through an opening 1a lin the upper end of the housing. is shown, a grille or screen 15 is preferabiy disposed in the opening 1li, and a curved air deecting member 50 is proilcod in the upner part oi the housing; for 'through the grilie My invention is limited to the use of a housing only to 'the extent indicated in the appended claims as it wiii become apparent this description p gresses 'that the core 12 could be mounted 'n any suitable passage such as, for instance,v passage :formed in a wall or the Eike..

The radiator core is preferabiy the t pe more uliy shown and described in my copending application Serial No. 112,3?6 May 28, 1926, Which has now matured into Patent No. 1,677 ,415? granted 17, 1928 and in this instance comprises piuraiity spaced tanks 16 17 which cornniu ica With eachother through a pluraiity o thv Walled tubes 18 provided with transverse` arranged hns 19. Mereiy for the purposes of this disciosure, i have illustrated the radiator core 12 as part oi a hot Water system,

means for connecting' the radiator core to 'the a hot Water syst/ero preferably comprising pipes 2() and 21 which communicate with the tanks 16 and 17, respectively, by means more fully shown and described in the aforementioned patent .wherein i have also disclosed e i. 7 support o.

defiecting' air outwardly Riv Sii)

- is a worm gear 32, the damper being preferably cut away as at 33 to vprovide space for the worm gear. Meshing with the worm gear 32 is a worm 34 rigidly secured to a rod or shaft 35 rotatably journaled in bearing members 36 and 37. rlhe bearing member 36 is preferably a bracket/mounted upon the radiator core 12and, in this instance, the bearing member 37 is formed of a iiat bar of metal also mounted upon the radiator core. The shaft 35 preferably extends through an aperture 38 formed in the housing 10 and is preferably provided with a hand-wheel or knob 39 whereby the shaft may be rotated so that the worm 34 will rotate the worm gear Obviously, rotation of the worm gear 32 will result in angular displacement of the damper 25 around the longitudinal axis of the shaft 27. lt will be noted that the damper 25 may be brought into a position wherein it substantially prevents a flow of air through the radiator core 12 and that itmay be brought into a plurality of adjusted positions to control the volume of air passino' through the core.

When the above described apparatus is in. operation, and'hot water is passing through the tubes 18 a column of air flows through the housing 10, the. air entering the open lower end of the housing and being discharged through the opening 14. 0f course, if the damper 25 has been brought into the position wherein it is shown in full lines in Fig. 3, there will be no appreciable flow of air through the radiator core and there will not be an eicientexchange ofheat between thehot water and the air surrounding thel tubes. Thus, an attendant may bring the damper 25 into position wherein it is shown in full lines in Fig. 3 when the temperature of the room is too high, or the attendant may adjust the damper 25 so that a predetermined temperature may be maintained within reasonable limits. lf the room is cold, the damper 25 is preferably brought to its fully opened position so that a maximum amount of air will pass through the .radiator lcore and the radiator core will function with maximum e ciency.

ln Fig. 4 l have illustrated another form of the invention embodied in heating apparatus which preferably comprises a radiator core 40 which is substantially identical in construction with the aforementioned radiator core 12. For the purposes of this dis'- closure the radiator core 40 is mounted in a housing 41 which may be considered to he substantially identical in constructionvv with the aforementioned housing 10. dour'naledv above the radiator core .40 is a roller 42 which is preferably ofthe Hartshorn type and preferably comprises a 'spring (not shown) which tends to wind a curtain or collapsible partition 44 around the roller. rlhe roller 42 is preferably mounted upon brackets carried by the radiator core,`one ,oi these brackets being resides? shown at 45. Securedto one end of the QOL lapsible partition 44 is a cable 47, or the equivalent, which extends through an aperture 48 formed in the housing 41 and is pro# vided with a knob 49, or the equivalent, at its 'outer end. Obviously, the collapsible partition 44 may be unrolled from the roller 42 by pulling upon the knob 49, the construction being such that any desired portion of the collapsible partition 44 may be unrolled to regulate they amount of air passing through the radiator core; The collapsible partition 44 functions substantially in the same manner as lthe aforementioned damper 25 and may be employed to regulate the temperature of a room in which the radiator core 40 is placed.

The collapsible partition 44 may be made of any suitable material which is suiiiciently flexible to permit `its being rolled upon the roller 42. In some instances, l prefer to form the collapsible partition 44 from a plurality of strips of metal which arepivoted to each other.

Having thus described by invention, it is obvious'` that various immaterial modiiications may be made in the same without departing from the spirit ofl my invention; hence l do not wish to be understood as lim* iting myself to the exact form, construction. arrangement and combination of parts herein shown and described or uses mentioned.
